Development and dosimetric verification of static SHArc: Step‐and‐shoot carbon ion arc therapy for LETd escalation in pancreatic tumors

open access: yesMedical Physics, Volume 52, Issue 10, October 2025.
Abstract Background Carbon ion radiotherapy (CIRT) offers higher linear energy transfer (LET) and superior relative biological effectiveness, making it a promising option for treating hypoxic, radioresistant tumors. Spot‐scanning Hadron Arc (SHArc) therapy enables dose‐averaged LET (LETd) escalation in the tumor but increases planning and setup ...

The high-energy hadron spin-flip amplitude at small momentum transfer and new AN data from RHIC [PDF]

open access: yes, 2004
In the case of elastic high-energy hadron-hadron scattering, the impact of the large-distance contributions on the behaviour of the slopes of the spin-non-flip and of the spin-flip amplitudes is analysed.

The Quest for the Quark‐Gluon Plasma From the Perspective of Dynamical Models of Relativistic Heavy‐Ion Collisions

open access: yesAstronomische Nachrichten, Volume 346, Issue 7-8, September 2025.
ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

Measurement of the cross-section for producing a W boson in association with a single top quark in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV with ATLAS

open access: yesJournal of High Energy Physics, 2018
The inclusive cross-section for the associated production of a W boson and top quark is measured using data from proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV. The dataset corresponds to an integrated luminosity of 3.2 fb−1, and was collected in

Two Micron‐Size Dark Dimensions

open access: yesFortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Measurement of the k t splitting scales in Z → ℓℓ events in pp collisions at s = 8 $$ \sqrt{s}=8 $$ TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2017
A measurement of the splitting scales occuring in the k t jet-clustering algorithm is presented for final states containing a Z boson. The measurement is done using 20.2 fb−1 of proton-proton collision data collected at a centre-of-mass energy of s = 8 $$
